To all whom 'it may concern.'

Be it known that I, ELMER A. SPERRY, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga ad State of Ohio, haveinvented new and useful Improvements in Centrifugal Machines, of whlchthe following is a specicatlon.

My invention relates to. centrifugal or hydr -extractora and itspecially -relates to continuously acting apparatus ofl this -characterand consists in means for causing 'a discharge movement of thematerials, especially granular and Inobile 1naterials, toward adischarge point and from a point at which the material is deliveredWithin the centrifugal device, and it consists essentially in apparatusdesigned to bring about this end, the nature and construction of whichis fully described herein, and the essential features o-f noveltypo-inted out in the claims hereto annexed and forming a part hereof.

The means employed in the present invention are extremely simple, andmay be con structed in various forms, and will readily be understoodfrom the drawings herewith, which show acontinuous centrifugal apparatus embodying one form of construction which serves to illustrate theaction of the device; but the invention should in no wise be limited inits scope to the construction shown in accompanying drawings, in which;

Figure 1 is a vertical section of one form of the apparatus; Fig. 2 is adiagrammatic view of the rot-ating basket showing a plurality ofrotating strippers or ejectors and other details. Fig. 3 is an iso-latedView of a pair of ejectcrs o-f different lengths and angles, showing apower connection; Fig. 4 is a form of ejector withla screwlike blade orblades; Fig. 5 is an alternate form 0f ejector disk or blade; Fig. Gillustrates a roller bearing for mounting or journaling the rotatingejector, also other details,v.together with a hollow form of ejectordisk or blade.

A rotating basket offany' of the usual forms or constructions isillustrated 10, supported by the central shaft 11 through the medium ofthe base plate 12 Ihaving radial webs 13 radiating from a central hublet and keyed andsecured to the conical part of the shaft 1l.Thisshaft'may protrude from below, or it may depend from the usualbearings and suppo-rt above, which form 1s de signed to bte-illustratedin the drawing.

basket may be straight sided, or the sides may be o-f any contour. Forsome purposes, however, it is found preferable to make it of the conicalshape illustrated, where it narrowsto the discharge end, which .may ormay not be furnished with the ring 15. In the present instance this ringis shown to have an outward and downward inclined projection or lip. Thebasket 10 is furnished with the usual perfor-ations, not be reinforcedby other rings 16 as occasion demands. Surrounding the basket is theusual stationary casing 17 supported upon' standards or One or more ofthese risers are furnished with means such, for instance, as the rod orrods 20, the nature and use of.which will be described below. The casing17 terminates below in a channel 21, which for` of which is considerablyinclined, as shown by thedott-edY lines, and at its lower pointcommunicates with the discharge pipe 25 .leadingin any directiontherefrom, preferably downwardly as illust-rated. The inner and lowercavity terminates near the top of the basket, but preferably by anint-urning projection just under the overhanging ring 15. To afford easyaccess, covers may be used upon these cavities which may inclose theentire'apparatus or its outejgjy portion only, which latter arrangementillustrated in the drawing by the section`lcovers 26 which may befurnished with N handle 27 and derive their support in any suitablemeans,v as, for instance, the hoolls 30 engaging the L-shaped ring o rprojection 31, or they may be still more securely locked in position byany form of jointor tongue and may or may risers 18 of any suitable andgroove, one form of the latter being shown. The apparatus lbeingdesigned'for continuous operation, it is providedfwith both theinduction and eduction apparatus which is adapted to this end.` Any formof induction apparatus instance; the feed tube 33 having a receivingbell4 and a discharging rbell .or ori-tice 35, and maysurrcund in partthe cent-ral shaft l1 and be provided with. the sleeve 36 whichldoesnotnecessarily engagethe shaft.

The bracket 44 may be supported inany Amanner so as tobe adjustable in any of thevarious manners above described.

For certain purposes it becomes necessary to wash, steam, cook, agitateor otherwise treat the contents of the basket, preferably during theprocess of spinning or treatment under the centrifugal action. Tofacilitate this-process and to cause it to be very much more effective,it is thought wise to apply the special treatment mentioned through therotating disksior blades, but in this instance they are made hollow andsuitably apertured for this purpose, inasmuch as these disks'continually enter into and are constantly deeply cutting the mass of thesubstance under treatment, 'andinasmuchas this requires only slightalteration in the structure of therotating element. Details have beenillustrated in Fig.' 6 of one form of the device lwhich may fulfil thedouble purpose ofacting as an ejecting means and at the same timeperform the functions of steaming, heating, washing, or the'like. Fig.,6also serves to illust-rate not only resilient support, piped connection,but also one form of ball or roller bearing. Upon the exterior of thesleeve 41 'are slipped thimbles 70, which may have apertures 71communicating with the interior of the sleeve 41, vwhich is in turncommunicated with the hollow stem 43 by lateral vents 72. .Betweentlie'lower tliimbles and the part 73 is iinpinged the lower half of thein'closed disk 42 -42. rlhese disks are preferably given an invertedspherical dish 7 bringing the peripheral edges together at point 74,which edges may be notched as shown at 7 5 or ncaa` the edges a perturesmay be provided as shown at 76. This de eiiptioii covers each member ofthe series of pairs of disks 42-'42,.the interiors of which will be seento communicate with the pipe 19. Thus it will be seen that a pressure,either negative or positive, of a liquid or `gas communicatedto pipe19.v

It will ventcommunication with the exterior *ta-ins the packing 78 impinged by"follower 79, the lower' edge of the body serving to impinge the edgesof all of the disks 4 2 and tliimbles 70. The ball bearing at the baseof the rotating part is inclosed in the cap 46,

the rollers ,being impinged between the lower race 45 and' the upperrace 80, the former `being supported upon the pin depending from thelower end of the stein 43, and the latter finding its support in thespindle 41 below. the projection 73.

Having now described my invention. and one method of carrying itsessential details into effect, its use and operation will be apparent.It will be assumed that the basket 10 is rotating'at a constant speedsuited to the special material to be treated or dried. This Amaterial inits wet sta-te flows into the tube 33, being urged downwardly byprojections 37 of essary, arriving vupon the bottom plate of Itquickly-takes centrifugal force carries it outwardly and upwardly on thesurface l2 until the peripheral upward bend directs` it on to theperforated port-ion `1O of the basket proper. rThis basketmay receivethe usual coverings, differing with different materials, upon which thesubstance accumulates as the liquids are forcibly ejected, this going onclear around on the interior surface in the As the vm'aterialJvit-hinthe basket is spun at one -or more points in its revolution, itencounters the blade or blades or the series of disks 40 upon the ste-m41 which is power driven through lthe roller bearings, such as have beenillustrated' at 45. The periphery of the blade or disks cut. into t-hesubstance to a greater 'or less depth and the blades or disks are causedto rotate through the impingement thus secured. This rotation` is foundto take place with more `virfor than would be expected, owing to thefact that the crystals or substance through the intense centrifugalaction becomes exceedingly dense and` forms a compact mass against theinner. wall of the basket, that is, the blade or disk takes, on a motionthat is in the same direction and a peripheral s peed that approximatesthat .of the material within and on the inner wa/ll of the basket; thisis especially true with the spiral form. The speed ofthe blade or blades40 will at once be seento be adifferential speed, and for 'some purposes.is obviously more suited to ,the performance of its functionsrby beingthus differential, either if driven through be obfreedom of rotationserved that the simple cutting of the rotation of the blade or blades ordisks into the moist mass as it sweeps past'. the region of therotatable member would accomplish nothing in point of movement ortransport of the masses from one point to another. lt, however, availsas a means of treatment of the substance constituting the mass, as hasbeen exj'ilained in connection with the form of apjpiaratus deseribet'lin Fig. (l, but as this is a secondary object, the primalobjecta'namely, that of mnving and finally ejecting the dry material isnot accomplished if the axis of the rotatable men'iber remains vin theplane of the shaft 1l. or the plane of parallel radii of the basket. lf,however, this axis'is tilted out of this plane, even to a 'very slightdegree, in such a manner that its lower end trails with the. motion of'the basket, so that the portion of the blade or disk' which comes nextto or is tangential to the inner will of the revolving basket, or thatpart of such blade as impinges the material upon the inner wall of thebasket, is out of the transverse plane of basket the desired resultbrought about.

lllhen the-blades are disk-like, as in Fig. 1, it is not necessary tothe function that the speed be ditl'erential, though usually this is thecase, through the imperfect driving scoured by in'ipingelnent as stated.1When the relation of angle and speed are as stated, a marked changecomes over the drying masses within the basket, and they are found togradually more upi'ardly, being dried more and more as they are spread,mobilized and agitated through lthe action of the. series of rotatingdisks. This gradual yet continuous upward movement of the mass persistsuntil the .top of the basket is reached, when it is found to be forcedoutwardly over the edge and in this manner ejected and rcv moved rlearof the basket, being suitably caught as by [lying into the outercircular cavity 2.2i, and finally passing out through the tube or tubes2T vprovided for this purpose. lhe reason for the upward movement of themasses will be apparent from Fig. 1. The tilting of the blades or theirangle in theregion of inipingemeat is such that they enter the masses ala lower point than that at which they leave the masses, this causing aslight lifting or upward movement equal in extent to this elevation ofone end of the chord over the other, this chord representing thein'nnersion depth of each sweep of the blade. or each disk into themasses. For some conditions or characters of materialit may be foundpreferable to 'use a plurality of blades or groups of disks rotatingupon their axes as illustrated in Fig. 2. When so used, they areadjusted to height in a certain relation to each other, which, for thebest effect, should be a half or a third of the pitch distance betweenadjacent blac es,

lawrence as the case may be, dependent upon a num.- ber of groupspresent. The action of such a plurality of groups consists of a slightelevation of the material by each group, such that the blade ordisk 40of the next group will catch and continue the upward move-v ment. Thegreater the angle of the blade at the point of impingement the morerapidly is the material removed, and the less the angle the longer thematerial is retainedhence, slower its ejection and the drierA the.

material. The incidental function of this device as an agitator to themass, thereby greatly facilitates the drying or other treatment, is avery lvaluable one as it is found to still further facilitate and hastenthe action. The action of the hydro-extractor, provided with thisdevice, becomes a continuous one, and the basket requires no stop pingor even change in speed while treating a large quantity, even many tonsof material. It has been estimated that the increase of capacity of a.given centrifugal with granular material is many times the amount ofwork performed by the old method.

Where the masses tend to become hard as they are compacted by thecentrifugal action, the notched blade or disk shown in Fig. 3 may beemployed. there itis desirable that the material be thinned downat anypoint in the basket, as, for instance, in the center of the height ofthe basket to save undue strains in this portion or at the top of thebasket to facilitate the removal of the material at a given point, thearrangement shown in Fig. 3 may'be employed, where the material iselevated to a point by the slowerl processand then removed more rapidlyby the rotar y ejector which is placed at a greater angle as shown. Theliquids are drained in the usual manner by gutter 21, discharge pipe orits equivalent 22. The roup of disks may be supported and adjusted byany well known means, one foi-1n of which is shown in Figs. 1, 2 and 3,withl an alternate form in Fig. (i. The remow; of the rotating member asa whole is facile tated by wheel 50 driving a pinion which eooperateswith rack 4S upon the stem 20. 'libe tilting action is secured betweenthe stem ll2 and the lsocket 17 as is also the depthito which the disksare forced into the masses of substances contained in the basket, thislatter by adjusting the stem 52 inwardly and outwardly from the socket.The screws 51 and 53 serve to clamp the parts into position afteradjustment. The angle of the blades isillustrated in Figj and Fig. 4,.

and also in Fig. 1, the arrow about the shaft 11 indicating itsdirection of movement. When it is desired to simultaneously treat thesubstance as Well as eject, the device takes the form illustrated inFig. 6, where the heating, moistening, or other treatment is in partdelivered into the interior masses of the material through the disksthemselves as they enter the substance. It is designed to use the partssubstantially 'as and in the relation shown. It is apparent, however,that some may be omitted and others may or may not be substituted, andthe invention extends to such use. y
